Often, the burden for caring for people suffering depression and other types of mental illness falls on family members.

Whether through giving practical care or emotional support, more than two million Australians take on that caring role.

Carers suffering high levels of stress

Research released by Beyond Blue and the Hunter Institute of Medical Research shows the stress and isolation of caring for a family member with depression is taking its toll.

Jaelea Skehan, the acting director of the Hunter Institute of Mental Health, says more than 70 per cent of people who live with or care for someone with depression are themselves suffering from high levels of psychological distress and they are in need of immediate help.

The health of carers is often an afterthought for doctors, despite the high risk of carers themselves developing mental illness.

The Hunter Institute's research found there are many barriers for mental health service providers in delivering support.

It is not routine practice for doctors to address the health needs of the carer and even when support is offered, there is a lack of information about the effectiveness of that help.

Mental illness suffered by carers is also a hidden problem - as many of those who provide care for people with depression do not see themselves as a carer and so do not ask for help.

"A young carer who is not supported is more likely to have poorer academic achievement and more likely to end up in the criminal justice system." Rob Ramjen from the Schizophrenia Fellowship of NSW says.

Ms Rudduck is studying to be a teacher, while Mr Isaac is training to be a mental health nurse.

"I realised I wanted to become one and give back to the community and see how my experiences can help other people," he said.
